IMPROVEMENT IN FLOWS.

Specification forming part of Letters Patent No. 136,36 1, dated March4, 1873.

To all whom it may concern:

Be it known that I, NICHOLAS BURCH, of North Fairfield, in the county ofHuron and State of Ohio, have invented a certain new and Improved Plowand I do hereby declare that the following is a full, clear, andcomplete description thereof, reference being had to the accompanyingdrawing making part of the same.

Figures 1 and 2 are side views of the invention. Fig 3 is a top view.

Like letters of reference refer to like parts in the several views.

The nature of this invention relates to the construction and arrangementof an iron standard, colter-strap, and wood beam of a plow, all of whichare so combined that said beam is firmly secured to the standard for thepurpose of obtaining lightness, simplicity, and strength to the plow.

In the drawing, A represents a wooden plowbeam. B is the standard towhich the beam is secured. On the upper end of the standard is formed ashoulder or rest, 0, having a flange, D at the side, as shown in Figs.1, 2, and 3. The beam rests upon said shoulder and is secured thereto bybeing bolted to the flange D by means of the bolts E, which bolts arealso used for attaching the colter to the beam by means of the strap Fon the side of the flange D, as shown in Figs. 1, 2, and 3. The beam isalso further fastened to the standard by the bolts G, which pass throughthe beam and shoulder, as seen in the drawing.

By this means the standard, beam, and colter-strap are firmly united,whereby is obtained to the plow lightness and simplicity, therebysecuring all the advantages of the elasticity and lightness of thewooden plow combined with the advantages of the iron-beam plow in thematter of the largeness of the throat peculiar to the iron plow withoutits great liability to break, which the iron beam is very liable to whensubjected to lateral strain, to which all plows necessarily are, more orless.

In this invention the colter-strap is fastened to the iron standardagainst the side of the flange instead of securing it to the side of thewooden beam, as is done in the common wooden plow; hence, the beam isnot subject to the wearing influence of the colter, and therefore willlast longer.

In this manner of attaching the colter to the beam the bolts E are madeto do double duty, by securingthe beam to the standard and the colter tothe beam.

The flange D'gives additional strength to the standard, and the means,in connection with the bolts, of holding the beam and colterstrap inplace.

Claim.

What I claim as my invention, and desire to secure by Letters Patent,is-

In the construction of plows, the wood-beam A and iron standard Bprovided with the col ter-holder F, and having a shoulder, O, and flangeD, in combination with screw-bolts, or their equivalents, for securingthe said beam and sta ard together, substantially as and for the purposeset forth.
